The board feeding unit 21 is used for moving in, positioning and moving out the substrate 11, the pre-welding unit 22 is used for preparing the bus bar 12 and the outgoing line 13 with set lengths and positioning the bus bar 12 and the outgoing line 13 according to set positions, the transfer manipulator 23 is used for taking the bus bar 12 and the outgoing line 13 from the pre-welding unit 22 and welding the bus bar 12 and the outgoing line 13 onto the substrate 11, and the outer sealing plate 25 is used for shielding the pre-welding unit 22.

When the substrate 11 moves to the feeding streamline 211, the X-direction centering mechanism 213 is lifted from the lower part of the conveying surface, then the substrate 11 is clamped from the X-direction two sides, and the Y-direction centering mechanism 214 directly clamps the substrate 11 from the Y-direction two sides, so that the position of the substrate 11 during total welding can be ensured. The whole bus bar outgoing line combination pre-welding integrated machine 2 is used as a working station in the whole production line, and in order to save space, the manufactured solar module 1 generally returns to the inlet along the original conveying direction, but returns to the inlet of the production line through a return material flow line 212.
As shown in fig. 7 and 9, the pre-welding unit 22 includes a welding station 221 located in the middle, a bus bar stock component 223 and a lead wire stock component 224 separately located on two sides of the welding station 221 and a material taking manipulator 222 located on an outer side of the welding station 221Y, where the material taking manipulator 222 includes a first mechanical arm 2221, and a first busbar suction cup group 2222 and a first lead wire suction cup group 2223 disposed at a free end of the first mechanical arm 2221, and the first busbar suction cup group 2222 is in a parallel relationship with the first lead wire suction cup group 2223.
The bonding stage 211 is a transfer mechanism for the bus bar 12 and the lead wire 13. The material taking manipulator 222 firstly takes the bus bar 12 with the fixed length cut from the bus bar material preparing component 223 and puts the bus bar 12 on the welding table 221, then takes the lead wire 13 with the fixed length cut from the lead wire material preparing component 224 and puts the bus bar 12 and the lead wire 13 on the welding table 221, and places the bus bar 12 and the lead wire 13 on the welding table 211 in a set relative position to wait for the transfer manipulator 23 to take the bus bar. Because the action of picking and placing the bus bar 12 and the action of picking and placing the outgoing line 13 are similar, the picking manipulator 222 shares one first mechanical arm 2221, and simultaneously, the picking of two materials (the bus bar 12 and the outgoing line 13) is realized, and the part cost is saved.
As shown in fig. 8, the welding stage 221 includes a positioning bracket 2211 shaped like a Chinese character 'tu', two Y-direction slide rails 2212, and two pre-welding mechanisms 2213, the positioning bracket 2211 slides along the Y-direction slide rails 2212, the positioning bracket 2211 includes two bus bar brackets 22111 arranged in the X-direction and one lead wire bracket 22112 arranged in the Y-direction, the lead wire brackets 22112 vertically intersect with the two bus bar brackets 22111, and the pre-welding mechanisms 2213 are located on one side of the intersection position of each bus bar bracket 22111 and the lead wire brackets 22112.
In the present embodiment, the bus bars 12 and the lead wires 13 are vertically and horizontally distributed on the substrate 11, wherein one section of the lead wires 13 is vertically and linearly distributed, and the two sections of bus bars 12 are horizontally and parallelly distributed, so that in order to increase the welding efficiency, the two pre-welding units 22 simultaneously operate from two sides, and the partial bus bars 12 and the lead wires 13 are pre-welded into a pre-welded body by the pre-welding mechanism 2213. If the arrangement of the bus bar 12 and the outgoing line 13 is not in the shape of a letter, the structure of the positioning bracket 2211 may be different. The position of the positioning bracket 2211 can be finely adjusted along the Y-direction slide rail 2212, so that the positioning bracket can be simultaneously in the operation range of the material taking manipulator 222 and the transferring manipulator 23, and mutual interference of the two manipulators is avoided.
As shown in fig. 3 and 5, the transfer robot 23 includes a second robot arm 231 and a total gripper 232 disposed at a free end of the second robot arm 231, where the total gripper 232 includes a flange plate 2321 connected to an end of the second robot arm 231, a gripper frame 2322 mounted with the flange plate 2321 as a center, a second bus bar suction cup group 2323 disposed on lateral beams on two sides of the gripper frame 2322, a second outgoing line suction cup group 2324 disposed on a middle longitudinal beam of the gripper frame 242, a camera and a light source 2325 disposed on a lateral beam in the middle of the gripper frame 2422, and a total welding mechanism 2326 disposed at two ends of the lateral beam on one side of the gripper frame 2322.

Under the condition that the light source is illuminated, the camera shoots and determines the specific position of the pre-welded body, the second mechanical arm 231 can properly adjust the position and the angle of the total grip 232, the second bus bar sucker set 2323 is utilized to suck the position of the bus bar 12 of the pre-welded body, the second lead wire sucker set 2324 is utilized to suck the position of the lead wire 13 of the pre-welded body, the pre-welded body is moved onto the substrate 11 by the transfer mechanical arm 23, and then the total welding mechanism 2326 is utilized to complete the total welding. If the arrangement modes of the bus bar 12 and the outgoing line 13 are different, the position settings of the second bus bar sucker set 2323, the second outgoing line sucker set 2324 and the total welding mechanism 2326 can also be adjusted correspondingly.

s3, upper plate: in the execution process of the steps S1-S2, the feeding streamline conveys the substrate to the middle part along the X positive direction, and the X-direction centering mechanism and the Y-direction centering mechanism are matched to finish centering and positioning of the substrate;
s4, total welding: the transfer manipulator picks up the pre-welded body, positions and places the pre-welded body on a substrate, and the total welding is completed by a total welding mechanism to obtain a solar module;
s5, discharging: after welding is finished, the X-direction centering mechanism and the Y-direction centering mechanism are reset, and the feeding streamline continuously moves the solar module out of the next station along the X-axis forward direction.
